Allen-Bradley 2711-K3A17L1 HMI Keypad

Allen-Bradley 2711-K3A17L1 PanelView 300 Standard Monochrome 3-inch keypad terminal with RS-232 DF1 communications is a compact HMI designed for local control panels. It runs on 11–30 V DC power and, as a 300-series keypad terminal, draws up to 10 W for typical operation. The unit features a 3-inch monochrome LCD display paired with a four-key keypad (F1–F4) capable of 2,000,000 actuations, making it suitable for simple operator input and status display in rugged industrial environments. Memory includes 240 KB of nonvolatile storage and 170 KB of RAM for application runtime and data objects. The keypad enclosure measures 133 × 111 × 48 mm and weighs about 284 g, and the device provides RS-232 (DF1) communications with no printer port, aligning with its role in PanelView Standard 300 configurations. As part of the Series A PanelView Standard family, 2711-K3A17L1 is a fixed-function, non-touch HMI intended for straightforward machine interaction, where a dedicated keypad interface plus a compact monochrome display delivers reliable, low-profile operator feedback and input for DF1-connected controllers.
